This invention relates to forming appa ratus, and moreparticularly to forming ap- `pa'ratus.comprising'dies movableinto" pressing Yengagementv withl each other..

Y "llheobject of the :invention is to provide improved .t apparatus for forming articles from fiexible material. .Y Y

One embodiment of the invention is par--k ticularly adapted to'v formv cones for y. loud speakers ofv the type'shownin the copend` ing application of Norman H. Rieker, Serial No.1592,675, filed October 6, 1922. This embodiment'of the invention comprises two die' members movable into pressing engagement With a relatively fixed die member to form a coneof the character describedfrom a paper blank, Oneof the movable members being wpivoted to a lever pivotally secured to the othermovabledie member which is inturn pivotally secured to the. xed die member. One of the movable diemembers cooperates Withthe Xed die member to form al seam of :two led es of the blank towhich an adhes'ive su stance has l been applied, vcam` 1 means `associated with the lever belllgoper-V k come ,apparent as the Vdetailed;V description progresses, reference being had tothe accompanying drawings, wherein 4 Fig. l is a plan viewof apparatusembody ingthe'invention; 1-
